The reflected light can be used to sense motion, such as distance, direction, and even velocity. The APDS-9960 is broken up into several different states that provide capabilities, such as proximity detection, a gesture engine, and color detection. The features that are most relevant to a gesture controller are the proximity and gesture states, which can be used to first sense a hand and then provide relevant data to determine which gesture motion was given to the system.
